MICHAEL MOMULLIN, OF DENVER, COLORADO.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent 1W- 312,283, dated February17, 1885.

Application filed Septemher17, 1834. (No model.)

To all whom it may concern:

Be it known that I, MIOI-IAEL McMULLIN, a subject of the Queen of GreatBritain, residing at Denver, in the county of Arapahoe and State ofColorado, have invented certain new and useful Improvements inLubricators; and I do declare the following to be afull, clear, andeXact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

My invention relates to improvements in oil-cups or lubricating devicesintended especially to be used on the movable parts of machinery, as onthe main rods of engines, &c., and belongs to the class of automaticfeeders wherein are combined a device to regulate the flow of oil to thebearing-surface, means for retaining settled sediment or dust in theoilreservoir, and preventing such sediment in the oil being carried tothe lubricating-point, and for constantly inspecting the condition andflow of oil, all of which will more fully appear hereinafter in thespecification and be pointed out in the claims.

In the accompanying drawings, which fully illustrate my invention,Figure l is a side view. Fig. 2 is a sectional view. Fig. 3 showstheplug detached, and Fig. 4 is a modification of my device.

A represents my oil-cup, which is formed of the arched top A, the flatbase A and the cylindrical side a. The top and bottom are made of metal,as brass,and are provided, respectively, with shoulders I) and I),through the former of which pass the rods B, provided with threadedpoints to enter openings in the shoulders b and secure the partstogether. The side a is a cylinder of glass fitting into grooves s inthe top and bottom, and circular washers s, of cork, rubber, or othersuitable material, are interposed between the ends of the cylinder andthe top and bottom of the cup, to prevent leakage. I

D is a conical screw-threaded washer or packing to close the opening inthe top A, through which oil is introduced, and it is perforated toadmit the passage of the regulator.

E is a hollow plug, which screws into a pipe, J, attached to the bottomA of the cup, through which the oil passes to the point of lubrication.The plug E has atits upper end,on the illside, a female screw to receivethe thread on the lower end of the regulator O, which first passesthrough the washer D and then down into the plug E, which latter hasseveral channels, d, meeting at the center, to convey theoil from thecup to the point of lubrication by the part I, which is of less diameterthan at the conjunction of the'channels d. The lower end of theregulator 0 being conical in shape, as it is screwed down into IE, itwill regulate the quantity of oil entering by the channels, and allow itto pass in large or small volume, as desired, through the feed-pipe I,or out it off entirely.

e is a shoulder or flange on the plug E,which prevents any settledsediment passing out of the cup through the channels leading to thefeed-pipe.

H is an opening in the pipe J, through which the quantity of oil passingthrough the pipe I can be observed. This is closed by a sleeve orsliding door, H.

J represents a pipe which carries the oil to the point of lubrication.It screws into the bottom A of the cup, and at the same time receivesthe screw-threaded lower end of the plug E.

To fill the cup, screw the regulator down into the plug E until theconical point enters and closes the feed-pipe I; then remove the washerD and introduce the oil, replace the washer, and by slacking theregulator by turning the knob c the feed through I may be regulated atwill. 7

In Fig. 4 will be seen a modification of my device. In this instance thebottom and sides of the cup are made integrally of metal, and the topwill screw on the side, and I dispense with the rods B and shoulders band b.

The condition of the oil may be inspected through a plate of glass, L,set in the side of the cup. In all other respects the details ofconstruction are the same.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1.- An oil-cup or lubricator formed of a me? tallic top and bottom,attached to a cylindrical glass side by means ot'shoulders andscrewrods, as shown, and having an opening at top to admit oil, whichopening is closed by a conical screw-threaded packing, said packingbeing perforated to allow the passage of the regulator, in combinationwith the flanged. and channeled plug and pointed regulator, allsubstantially as described.

2. In an oil'cup, the combination of the arched top A, having an openingto admit oil, said opening being closed by the perforated conicalscrew-packing D, with the glass cylinder at, the bottom A shoulders I)and Z), the washers s, the screw-rods B, the hollow plug E, and theregulator 0, all constructed and operating as described.

3. 111 an oil-cup, the combination of the top A, having oil-opening andscrew-plug D, the glass side or cylinder a, the bottom A", pro

vided with opening to receive the screw-plug E, and pipe J, havingflange 0, channels d, and feed-pipe I, and the regulating device 0, allsubstantially as shown and described.

4. The combination, in an oil-cup or lubricator, ofthe metallicbottomAihaving ascrewthreaded opening to receive the pipe J, and with side(ointegral with the bottom, and having an opening therein to inspect thestate of the oil, closed by a strip of glass, L, with the regulator- G,the top A, arranged to screw onto the side a, and the screw-plug E, thelatter provided with flange or shoulder 0, channels (Z, and feedpipe I,all as shown and described.

In testimony whereof I afiix my signature in presence of two witnesses.

MICHAEL hIUIVIULLIN.
